CAR-TRUCK.

VSpecification of Letters Patent.

Patented June 2, 1908.

Application filed June 1, 1907. Serial No. 376,880.

To all whom it may concern:

Be it known that I, EDWARD H. IrIAvER, a citizen of the United States of America, residing at Houston, in the county of I-Iarris and State of Texas, have invented new and useful Improvements in Car-Trucks, of which thefollowing is a specification.

This invention relates to car trucks, and

one of the principal objects of the same is to provide an arrangement of equalizers which will reduce the lateral swinging motion of the car when assing around curves or when striking a sight obstacle,'such as a slightly raised track end.

Another object of the invention is to rovide compensating transverse equalizer ars for the truck frame and bolster which will reduce the swinging motion of the car frame.

These and other objects may be attained by means of the construction illustratedin the accompanying drawings, in which:

Figure 1 is a plan view of a car truck provided with my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a trans-A verse sectional view on the line 3-3,-of Fig. 1, looking in the direction indicated by the arrows in said figure. Fig. 4 is a longitudinal sectional view on the line 4-4 of Fig. 1,

looking in the direction indicated by the ar-` Fig. 5 is a detail perspective view of Fig. 6 is a detail perspective view of one of the equalizer supporting bars. Fi 7 is a detail perspective view of the bo ster. n

`Referring to the drawings for a more particular description of my invention, the numeral 1 designates the truck frame, 2 are the journal boxes, 3 are the wheels, 4 are the bolster'springs, 5 are the equalizer bars, 6 are the truss rods, and 7 are the truck springs.

IOWS.

, These parts may be of the yusual or any suitable construction. The bolster 8 is provided with a pair of spaced su porting bars 9 secured to the upper side t ereof by means of suitable brackets 10 connected to the sides of the bolster by means of screws or bolts 11, saidbars 9 being connected at their ends b means of rods or pins,.12, which pass throu the bars 9 and through the upper ends of t e brackets 10, said rods or pins having reduced ends 13, said ends being screw threaded. Connected to the reduced -en'ds 13 are links 14, said links being held in place by means of nuts 15. The compensatlng or equalizing bars 16 are pivotallllisconnected at their ends to links 17 said l' being pivoted at their upper ends to lugs 18 extending upward froml a transverse supporting bar or plate 19 sef cured to the platform 20. The two equalizers 16 are pivotally connectedA centrally, as

at 21. The platform 20 is supported by rods 22, the ends of which are connected to links 23 pivotally connected at24 to yokes or stirrups 25 bolted to the cross bars 26.

As shown in the drawings a pair of the equalizers 16 are disposed upon opposite si es of the bolster 8, and connected thereto in the manner described. As a result of this construction and arrangement, the lateralvibration or swing of the c ar truck will be sustained upon the compensating' or equalizing bars 16 independently of the springs so that the jar of the car frame will bepractically reduced to a minimum.

By means of my construction the swinging motion of the car is materially reduced while the links 14 and 17 of the equalizing bars allow a certain degree of lateral motion,

which is essential to the smooth and easy..

running of the car. The equalizers keep the bolster and the springs always arallel, thus distributing the weight on bot springs, 1nstad of first on one side and then on the ot er.

From the foregoing it will be obvious that by means of my invention, the rolling stock upon uneven tracks; that the invention iscomparatively simple in construction, can be installed on passenger cars Without material e alteration in the structure of the truck, and will operate efficiently for the purpose referred to.

Having thus described the invention, what I claim is:

1. In a car truck, a pair of transversely disposed compensating or equalizing bars, said bars being pivotally connected together, links at the ends of said bars, one pair of 'said links being supported upon the bolsterfvand the other pair upon a supporting bar connected topa `platform under the bolster.

2; In a car truck, the combination of a bolster, a pair of compensating or equalizing bars pivotally connected together and sulported by links attached to the top of t e olster, said bars being supported upon links connected to a platform under the bolster.

3. In a car truck, a bolster, ,a platform un'- der the bolster, supporting bars connected to the to 1 of Exesterfequaizers irate-11,1 ing through saai-su arising has; and ru- @emerged together met prevideei vided reduced bar Enh pivetslily smpported apen bcrster suppertug' eormeetec together, connected tcm'the bers on seid petr'erm t@ which the equalizer@ ends of said equaizing bars, said being 20 5 are eenneeten by b f comme-ted to thef-j reded erds of cross n 41,4 om 8mm", me maling' g airs lor" ings@ ortn are m'y @g at' `eil-o car tcueksgeom baxrsprvetaly seosite links connectgsto the eqa cured together and ivoted tov bars and. pivotaly crmeeted to said therouter ernd`s @ne of said being lu M mpperted Upon bolster ami the other 1 `tesdimcmy whereof, I aixmy signature lrbu ou ab Gross bar (m the patterm under' in presence of two witnesses.
